Delaware County will begin mosquito spraying on Wednesday near Polaris Parkway after three
batches of mosquitoes in Columbus tested positive for West Nile virus.

The Delaware General Health District will fog the area bounded by Polaris Parkway, the Norfolk
Southern railroad tracks, Maxwell Avenue and I-71 after West Nile was found last week in Columbus
Public Health traps.

Columbus also will spray today southeast of Frebis Avenue and Lockbourne Road, and Thursday near
Blendon Woods Metro Park and an area northeast of Sawmill and Hard roads.

Franklin and Licking are the only central Ohio counties with positive samples so far, said
Richard Gary, state public health entomologist for the Ohio Department of Health. Other counties
are awaiting results.
